FIELD OF THE DISCLOSURE

The present disclosure generally relates to implementations of smartring wearable devices and, more particularly, to methods and devices fordisplaying information indicative of driving conditions to a driver viavisual projections from smart ring wearable devices.

BACKGROUND

Information pertaining to driving conditions of a vehicle and/or driverare valuable for navigation of the vehicle, ensuring safe operation ofthe vehicle, and lawful operation of the vehicle. Typically, operatorsof vehicles are provided, via a console display within the vehicle, witha limited amount of information pertaining to the vehicle (such as aspeed of the vehicle or operational statuses of various elements of thevehicle such as the motor, oil levels, heat levels, etc.). In typicalvehicles, information provided by the vehicle to an operator of avehicle is typically limited to the operational statuses of the vehicleitself.

BRIEF SUMMARY

As disclosed herein, a smart ring device is configured for displayinginformation indicative of driving conditions to a driver via a visualprojection (sometimes simply referred to herein as a “projection” or“projections”). The smart ring device allows for the presentation of amultitude of different factors and conditions to a driver of a vehicle(e.g., a wearer of the smart ring) during operation of a vehicle. Onebenefit of the smart ring device is that the smart ring may measurebiometrics of the driver and display indications of the biometrics suchas a heart rate, blood pressure, blood-oxygen level, etc. Further, basedat least in part upon the biometric information, the smart ring mayprovide indications to a driver of an operational state of the driver(e.g., a weariness level of a driver, an inebriation level, etc.) toindicate a potential risk of hazardous driving of the driver. The smartring may be easily worn by a user of the smart ring throughout theuser's day, and/or overnight, allowing the smart ring to track sleepinghabits and physical exertion allowing for the smart ring to moreaccurately determine physical states of the wearer of the smart ring,compared to other user associated cellular devices such as a cell phoneor step tracker. Additionally, the smart ring may display to a driverindications of environmental conditions, operating conditions of thevehicle, conditions of other drivers, conditions of other vehicles, ormay display driving risk levels based at least in part upon any of theconditions, or combinations of conditions.

The smart ring device can provide indications to a driver without thedriver having to remove any hands from a steering wheel of the vehicle,or having to shift their gaze to a central console, which can reduce therisk of hazardous driving, and/or unlawful driving.

The system may further include a power source disposed within the ringband configured to power the smart ring device, and a memory to storecomputer-executable instructions. The computer executable instructionsmay cause the processor to obtain information indicative of the one ormore driving conditions, and to control the projector module to causethe projector module to display visual indicia indicative of the one ormore driving conditions.

The communication module may be configured to provide communicationsbetween the smart ring device and external devices and systems. Thesmart ring device may communicate, via the communication module, with amobile device associated with the driver of a vehicle, wherein themobile device is configured to obtain information from sensors of thevehicle.

The system may further include a user input unit communicatively coupledto the processor.

The system may further include an optical source to provide opticalenergy and projection optics configured to project the optical energyfrom the optical source onto a surface to display the informationindicative of the one or more driving conditions. The system may alsoinclude an optical source disposed on the smart ring, and projectoroptics that are physically independent from the smart ring device andare configured to project optical energy from the optical source onto asurface to display information indicative of the one or more drivingconditions. Further, the system may include optical sensors configuredto receive optical feedback from a user, wherein the optical feedbackconstitutes a user input including one of a hand gesture, a handmovement, an input performed by a stylus, a gesture performed on thesurface of the projection, or a virtual interaction with the projection.

The system may further include biometric sensors configured to monitorbiometrics of the wearer of the smart ring, and further configured tocommunicate, via the communication module, biometric information to amobile device associated with the driver of the vehicle.

Theconfiguration 205 e may clip onto a conventional ring using asubstantially flat clip 210 g part of the housing and contain the smartring components in a platform 210 h part of the housing.

The configuration 205 f, on the other hand, may be configured to becapable of being mounted onto a finger of a user without additionalsupport (e.g., another ring). To that end, the housing 210 i of theconfiguration 205 f may be substantially of a partial annular shapesubtending between 180 and 360 degrees of a full circumference. Whenimplemented as a partial annular shape, the housing 210 i may be moreadaptable to fingers of different sizes that a fully annular band (360degrees), and may be elastic. A restorative force produced by adeformation of the housing 210 i may ensure a suitable physical contactwith the finger. Additional suitable combinations of configurations (notillustrated) may combine at least some of the housing features discussedabove.

The configuration 205 g may be configured to have two rings, a firstring 205 g 1 capable of and adapted to be mounted onto a finger of auser, and a second ring 205 g 2 capable of and adapted to be directlymounted onto the first ring 205 g 1, as depicted in FIG. 2. Said anotherway, the first ring 205 g 1 and the second ring 205 g 2 are arranged ina concentric circle arrangement, such that the second ring 205 g 2 doesnot contact a user's finger when the smart ring 205 g is worn. Rather,only the first ring 205 g 1 contacts the user's finger. Each of thefirst and second rings 205 g 1 and 205 g 2 of the smart ring 205 g mayinclude a body having flexible material. In addition, the first ring 205g 1 may include a first part, and the second ring 205 g 2 may include asecond part removably connected to the first part.

III. Example Surface Elements of a Smart Ring

FIG. 3 includes perspective views of example configurations 305 a, 305b, 305 c, 305 d, 305 e, 305 f, and/or 305 g of a smart right (e.g., thesmart ring 101) in which a number of surface elements are included. Thesurface elements may include sensors for detecting informationindicative of driving conditions, or receive information indicative ofdriving conditions from external devices. The surface elements may alsoinclude output elements for displaying information indicative of thedriving conditions to a driver.

The configuration 305 a is an example band configuration 305 a of asmart ring (e.g., smart ring 101). Some of the surface elements of thehousing may include interfaces 312 a, 312 b that may be electricallyconnected to, for example, the charging unit 130 or the communicationsunit 160. On the outside of the configuration 305 a, the interfaces 312a, 312 b may be electrically or optically connected with a charger totransfer energy from the charger to a battery (e.g., the battery 120),or with another device to transfer data to or from the ring 305 a. Theouter surface of the configuration 305 a may include a display 390 a,while the inner surface may include a biometric sensor 350 a.

Configurations 305 b and 305 c are examples of configurations of a smartring with multiple housing parts (e.g., the configuration 205 b in FIG.2). Two (or more) parts may be separate axially (the configuration 305b), azimuthally (the configuration 305 c), or radially (nested rings,not shown). The parts may be connected mechanically, electrically, oroptically via, for example, interfaces analogous to the interfaces 312a, 312 b in configuration 305 a. Each part of a smart ring housing mayhave one or more surface elements, such as, for example, sensors 350 b,350 c or output elements 390 b, 390 c. The latter may be projectormodules or elements of projector modules (e.g., output element 390 b) orhaptic feedback devices (e.g., output element 390 c), among othersuitable sensor or output devices. Additionally or alternatively, atleast some of the surface elements (e.g., microphones, touch sensors)may belong to the user input unit 170.

The configuration 305 d may be an example of a band and platformconfiguration (e.g., the configuration 205 c), while the configurations305 e and 305 f may be examples of the partial ring configurations 205 dand 205 e, respectively. Output devices 390 d, 390 e, and/or 390 f onthe corresponding configurations 305 d, 305 e, and/or 305 f may be LCDdisplays, OLED displays, e-ink displays, one or more LED pixels,speakers, projector modules, elements of projector modules or any othersuitable output devices that may be a part of a suite of outputsrepresented by an output unit (e.g., the output unit 190).

The configuration 305 g is an example of a band with a one or moreoutput devices 390 g disposed on an outer surface 310 g and an innersurface 311 g of the ring band. In embodiments, the output devices 390 gmay be disposed on first and second side surfaces 308 g and 309 g of thering band. Alternatively, the output devices 390 g may be disposedwithin the inner and outer surfaces 310 g and 311 g, or the first andsecond side surfaces 308 g and 309 g, of the ring band configured toproject an image to be viewed by a user of the smart ring configuration305 g. For example, in embodiments the outer and inner surfaces 310 gand 311 g or first and second side surfaces 308 g and 309 g may betransparent. The output devices 390 g may be configured to project animage from the entirety of the outer surface 310 g, the entirety of theinner surface 311 g, the entirety of the first side surface 308 g, orthe entirety of the second side surface 309 g. In embodiments, theoutput devices 390 g may be disposed on, viewable from, or projectimages from only a portion of each of the surfaces 310 g, and 390 g,and/or 311 g. Additionally, sensors may be operatively coupled to theconfiguration 305 g (e.g., elements and sensors of the user input unit170 of FIG. 1) to detect a user input to determine where and how animage should be projected from the output devices 390 g. For example, auser may press a finger or stylus on the outer surface 310 g to indicatethe information should be projected from the outer surface 310 g.Alternatively, the ring may be removed from a finger, or digit, of auser, or wearer, of the smart ring, and the user may press a finger orstylus on the inner surface 311 g to indicate that information should beprojected from the inner surface 311 g. As such, optics of theprojection from the outer surface 310 g may provide differentmagnifications or have different image projection capabilities (e.g.,color vs monochromatic images, higher/lower resolution images, etc.)than the projection from an inner surface 311 g, or another outputdevice 390 g. A user of the configuration 305 g may prefer informationto be selectively projected from the outer or inner surfaces 310 g and311 g, or the first and second side surfaces 308 g and 309 g, dependingon the type of information, potential content of the information, acurrent environment where the user is viewing the information, a desiredimage resolution, or depending on privacy concerns among otherconsiderations. Alternatively, a user may press on a surface to indicatewhere the information should not be projected from.

Elements of the user input unit 170 may be coupled to the output devices390 g and a user my press on a portion of the output devices 390 g toindicate that information should be projected from the portion of theoutput devices 390 g that was pressed. Additionally, a user may indicatewhere the output devices 390 g should project the information dependenton different types of user inputs (e.g., audio input, a visual inputsuch as a gesture in a projection, twisting of the ring, removal of thesmart ring from a finger or digit, placement of the ring on a finger ordigit, a physical orientation of the ring, a change in orientation ofthe ring, etc.). In embodiments, the smart ring configurations 305 a,305 b, 305 c, 305 d, 305 e, 305 f, and/or 305 g may include an inertialmotion unit (IMU) for detecting the orientation and/or the movement ofthe ring having one of the configurations 305 a, 305 b, 305 c, 305 d,305 e, 305 f, and/or 305 g. The orientation or a change in theorientation of the smart ring configuration 305 a, 305 b, 305 c, 305 d,305 e, 305 f, and/or 305 g may be analyzed by a processor of the smartring configurations 305 a, 305 b, 305 c, 305 d, 305 e, 305 f, and/or 305g to determine which of the output devices 390 a, 390 b, 390 c, 390 d,390 e, 390 f, and/or 390 g to project the information, or to determine aportion, or portions, of the output devices 390 a-390 g that are todisplay or project the information. In embodiments, the output devices390 a, 390 b, 390 c, 390 d, 390 e, 390 f, and/or 390 g may display orproject an indication of a message or information that is ready to bepresented to a user. The user may then provide the user input to thesmart ring, based at least in part upon the indication, to indicatewhich output device 390 g should display or project the information,and/or what portion of the output device should display or project theinformation. Enabling the user to indicate a portion of the display fordisplaying or projecting information may be useful in a number ofcontexts. For example, this feature enables a user to selectively viewinformation at a time and on a surface (e.g., on the windshield of acar, or on a table or other surface) when he or she alone can view theinformation, thus providing the user with privacy he or she might nototherwise have. Further, in some embodiments, the band may have adisplay or projector module that occupies a significant portion of theouter band. In such embodiments, portions of the display or projectormodule may not be viewable by the user (e.g., because those portions maybe viewable only from the palm-side of the hand). Thus, in suchembodiments it may be advantageous to enable the user to indicate adesired portion for display or projecting the information (e.g., aportion of the display or projector module that projects an imageviewable from the back-side of the hand).

Alternatively or additionally, the outputdevices 390 a, 390 b, 390 c, 390 d, 390 e, 390 f, and/or 390 g maydisplay or project the numerical value of the detected pulse rate.Projector modules of the output devices 390 a, 390 b, 390 c, 390 d, 390e, 390 f, and/or 390 g may project a visual indication of informationindicative of a pulse rate, blood flow, blood oxygen level, bloodpressure, skin salinity level, temperature, weariness level, acognoscente condition of the user, an inebriation condition of the user,or any other biological and biometric information to a user of the smartring. Additionally, the ring may project images and indications of astate of a user such as erratic behavior of the sure, sleepiness of theuser, stress level of the user, etc.

In embodiments, the output devices 390 a, 390 b, 390 c, 390 d, 390 e,390 f, and/or 390 g may display or project a visual indication dependenton detected vehicular statuses. For example, the smart ring maycommunicate with sensors of a vehicle, with a communication module ofthe vehicle, or with another device or network to obtain currentstatuses of the vehicle and parts of the vehicle. For example, theoutput devices 390 a, 390 b, 390 c, 390 d, 390 e, 390 f, and/or 390 gmay display or project a low fuel graphic or image to indicate that thegas in the tank of a vehicle is below a minimum threshold. The outputdevices may similarly display or project a graphic or image to indicatethat the heat of the engine of the vehicle is too high or a tire of thevehicle has an air pressure below a threshold. Additionally, the outputdevices may display or project a visual indication to presentinformation to the user indicative of an oil level, needed oil change,coolant level, exhaust fume legal compliance, break pad health, lowbattery charge, flat tire, alternator failure, tirealignment/misalignment, transmission issue, power steering fluid level,brake fluid level, transmission fluid level, windshield wiper fluidlevel, etc.

In embodiments, the output devices 390 a, 390 b, 390 c, 390 d, 390 e,390 f, and/or 390 g may display or project a visual indication dependenton vehicular operations. For example, the smart ring may communicatewith sensors of the vehicle, with a communication module of the vehicle,or with another device or network to obtain a current speed of thevehicle. The output devices 390 a, 390 b, 390 c, 390 d, 390 e, 390 f,and/or 390 g may project the numerical value of the speed (e.g., 32), ora graphic or color indicating that speed of the vehicle is above amaximum speed threshold or below a minimum speed threshold, and theoutput devices 390 a, 390 b, 390 c, 390 d, 390 e, 390 f, and/or 390 gmay present a different graphic or color if the detected speed isbetween the maximum and minimum speed thresholds. In embodiments, theoutput devices 390 a, 390 b, 390 c, 390 d, 390 e, 390 f, and/or 390 gmay display or project visual indications to present to a userinformation indicative of a speed of a vehicle, an acceleration of avehicle, a current altitude of the vehicle, the lane centering of thevehicle, a fuel efficiency of the vehicle, an autopilot function statusof the vehicle (e.g., autopilot is activated/not-activated), anautonomous driving function of the vehicle is operational, an autonomousdriving function of the vehicle is activated, air bags areactivated/de-activated, a seat belt is latched/unlatched, a temperatureof the environment inside of the cabin of the vehicle, etc.

In embodiments, the output devices 390 a, 390 b, 390 c, 390 d, 390 e,390 f, and/or 390 g may display or project a visual indication dependenton external factors or environmental factors in, and around, thevehicle. For example, the smart ring may communicate with sensors of thevehicle, with a communication module of the vehicle, with communicationmodules of other nearby vehicles, with a mobile device of the user ofthe smart ring, or with another device or network to obtain informationand statuses of nearby vehicles. For example, it may be communicated tothe smart ring that a nearby driver is driving erratically, and thesmart ring may display or project a warning message, a graphic, or thecolor red to indicate that the driver (e.g., the user of the smart ringdevice) should be cautious. Additionally, the output devices may displayor project visual indications, signals, and information indicative ofcurrent or predicated weather conditions (e.g., rain, snow, extremeheat, etc.), current external environmental conditions (e.g., wet/slickroads, fog levels, a visibility level, dangerous breathing air, externaltemperature, etc.), current conditions inside of the cab of the vehicle(e.g., the temperature, air quality, moisture level, etc.).

In embodiments, the output devices 390 a, 390 b, 390 c, 390 d, 390 e,390 f, and/or 390 g may output visual indications and signals toindicate many driving conditions during operation of a vehicle such asthe congestion of drivers along a road or planned trip route, thecurrent proximity of the vehicle to external objects outside of thevehicle (e.g., other vehicles, pedestrians, trees, etc.), or otherfactors associated with operation of a vehicle.

The output devices 390 a, 390 b, 390 c, 390 d, 390 e, 390 f, and/or 390g may display or project visual indications to a user of a smart ring,any number of driving conditions as described above. Driving conditionsmay be considered to be any element or factor that may have an influenceor impact on the operation of a vehicle. For example, the weariness ofan operator of the vehicle may be considered to be a driving condition,as well as the visibility of a road due to a rainstorm. The drivingconditions may include one or more of the examples above including,without limitation, any operation of a vehicle, status of a vehicle orpart of a vehicle, biometric of a user of the smart ring, operation ofthe smart ring, status of the smart ring, external environmentalfactors, and external driving factors. Additionally, it is envisioned,that the user of the smart ring may be a driver of a vehicle and thebiometric information may be used to determine the sleepiness of thedriver, inebriation condition of the driver, or otherwise, cognoscentecondition of the driver.

While described above as “displaying or projecting visual indications”,the output devices 390 a, 390 b, 390 c, 390 d, 390 e, 390 f, and/or 390g may provide other visual signals or outputs indicative of drivingconditions. For example, the output devices 390 a, 390 b, 390 c, 390 d,390 e, 390 f, and/or 390 g may each portray information to a userthrough flashes or optical pulses projector module, presenting images,characters, or symbols by the projector module, or presenting wholesentences and messages via the projector module. The output devices 390a, 390 b, 390 c, 390 d, 390 e, 390 f, and/or 390 g may include one ormore projector modules for projecting characters or symbols, andscrolling of characters or symbols, as described in simultaneousreference to FIG. 3, FIG. 4A, FIG. 4B, FIG. 4C, and/or FIG. 5.

V. An Example Smart Ring Projector Module for Displaying Information

FIG. 4A, FIG. 4B, FIG. 4C, and FIG. 4D are example illustrations ofsmart ring devices 480 a, 480 b, 480 c, and/or 480 d with outputdevices, such as any of the output devices 490 a, 490 b, 490 c, 490 d,490 e, 490 f, and/or 490 g, having a smart ring projector modules 482 a,482 b, 482 c, and/or 482 d for projecting characters, symbols, images,and animations indicative of driving conditions identified by the smartring devices 480 a, 480 b, 480 c, and/or 480 d. The projector modules490 a, 490 b, 490 c, and/or 490 d, each include optical sources 492 a,492 b, 492 c, and/or 492 d and projection optics 494 a, 494 b, 494 c,and/or 494 d. The optical sources 492 a, 492 b, 492 c, and/or 492 d areconfigured to provide optical energy to the projection optics 494 a, 494b, 494 c, and/or 494 d, for the projection optics 494 a, 494 b, 494 c,and/or 494 d to project an image, visible character, symbol, or othervisual indication of information pertaining to driving conditions, ontoa surface. In embodiments, the optical sources 492 a, 492 b, 492 c,and/or 492 d may include LEDs, LDs, OLEDs, a black body source, amonochromatic optical source, or other sources of optical energy.

Inembodiments, the projector modules 480 a, 480 b, 480 c, and/or 480 d maybe configured to project on a multitude of surfaces such as a dashboardof a vehicle, a front windshield of a vehicle, a window of a vehicle, aceiling of the inside of a cab of a vehicle, a table, a designatedsurface for displaying the information, or another surface for aprojection to display information to a driver.

The smart ring device 480 a of FIG. 4A is an example of a smart ringdevice having the projector module 490 a entirely on an outer surface484 a of a ring band 482 a of the smart ring device 480 a. The opticalsource 492 a is disposed on, or inside of, the outer surface 484 a. Theprojection optics 494 a are disposed on the outer surface 484 a, or onthe optical source 492 a configured to project the optical energyprovided by the optical source onto a surface 496 a to form an image,visible character, symbol, or other visual information indicative ofdriving conditions.

In another embodiment, as illustrated in FIG. 4B, the smart ring device480 b may include a projector module 492 b that has the optical source492 b disposed on, or inside of, an inner surface 486 b of a ring band482 b. The projection optics 494 b may be disposed on, or within thering band 482 b away from the optical source 492 b to receive opticalenergy from the optical source 492 b to project an image, character,symbol, or other visual information indicative of driving conditions,onto a surface 496 b. The smart ring device 480 b of FIG. 4B may furtherinclude projection optics disposed on top of the optical source 492 b,or on the inner surface 486 b of the ring band to receive the opticalenergy from the optical source 492 b before the optical energy isprovided to the projection optics 494 b disposed on, or inside of, thering band 482 b.

In yet another embodiment, illustrated in FIG. 4C, the smart ring device480 c may include a projector module 490 c with the optical source 492 cdisposed on, of inside of, an outer surface 484 a of a ring band 482 cof the smart ring device 480 c. The projection optics 494 c may bephysically independent from the ring band 482 c, and be spatiallyconfigured to project an image, character, symbol, or other visualinformation indicative of driving conditions, onto a surface 496 c. Theprojection optics 494 c may be held by a mount 498 c or other structurefor mounting the projection optics 494 c. The mount 498 c may be astand, a clamp, a mirror mount, a lens mount, an optical rotatablemount, a motorized mount, a prism mount, a filter mount, a diffractiongrating mount, or another mount capable of mounting the projectionoptics 494 c.

In still another embodiment, illustrated in FIG. 4D, the smart ringdevice 480 d may include a projector module 490 d with the opticalsource 492 d disposed on, or inside of, an outer surface 484 d of a ringband 482 d. The projection optics 494 d may be positioned by a mount 498d relative to the optical source to project an image, character, symbol,or other visual information indicative of driving conditions, onto asurface 496 d. The mount 498 d may be coupled to the ring band 482 d andmay be removable from the ring band 482 d. The mount 498 d may becapable of mounting multiple optical elements of the projection optics494 d for projecting the image. In embodiments, the mount 498 d may bepart of a housing component (e.g., the housing component 210 e of FIG.3) or may be attachable to a platform (e.g., the platform 210 h of FIG.3).

In envisioned embodiments, a projector module may project images, orvisual images indicative of driving conditions from a side surface of asmart ring device (e.g., the first and second side surfaces 308 g and309 g of FIG. 3). For example, LEDs or LDs may be disposed on sidesurfaces to display an image of a circle that changes color dependent ondriving conditions. A portion of a circle may be displayed to indicatespeed (e.g., a speedometer) or another gauged value or measurement. Inembodiments, projection modules configured to project visual informationindicative of driving conditions may include projection optics, or maynot include projection optics when a laser or LDs.

The projector modules 490 a, 490 b, 490 c, and/or 490 d may displaycharacters, symbols, words, or sentences, to a user of a smart ringdevice. For example, as illustrated in FIG. 4A, the projector module 490a may project numerals (e.g., “32”) that may be indicative of a speed ofa vehicle, a number of miles traversed during operation of a vehicle,the number of miles left to get to a destination of a vehicle, biometricinformation of a wearer of the smart ring device, or another metric orother information as described herein. As illustrated in FIG. 4B, theprojector module 490 b may project a caution message that reads“Caution: Slick Roads Ahead.” The message may be too long to display atone time on the surface 496 b. The output device 490 may then displaycharacters, symbols, words, and/or sentences sequentially in frames, forexample, as illustrated in FIG. 4C, displaying the word “Caution” for afew seconds, and then displaying a new frame with the words “Slick RoadsAhead,” (not illustrated in FIG. 4C).

Displaying messages in frames allows for the projector modules 490 a,490 b, 490 c, and/or 490 d to display longer messages, but may not besuitable for smooth reading of entire sentences or text messages.Therefore, the projector modules 490 a, 490 b, 490 c, and/or 490 d maydisplay information in the form of a message in a manner that themessage is scrolled across the surfaces 496 a, 496 b, 496 c, and/or 496d. The projector modules may project and scroll any characters, symbols,sentences, colors, images, or messages indicative of one or more drivingconditions as described above.

Additionally, the projector modules 490 a, 490 b, 490 c, and/or 490 dmay display (e.g., by way of scrolling) a symbol or series of symbols,such as a happy face, thumbs up, check mark, or other symbol that may beindicative of a driving condition. For example, a smart ring device mayattempt to establish a communication link with a mobile device of theuser of the smart ring device, or with a communications module of avehicle being driven by the user of the smart ring device. The projectormodules 490 a, 490 b, 490 c, and/or 490 d may display a check mark toindicate that the communication link has been successfully established.

FIG. 5 is a flow diagram of a method 550 for controlling the scrollingof information across a projection surface via projection from aprojector module, such as by the projector modules 490 a, 490 b, 490 c,and/or 490 d across corresponding surfaces 496 a, 496 b, 496 c, and/or496 d as illustrated in FIG. 4A, FIG. 4B, and/or FIG. 4C. Scrolling ofinformation and controlling the scrolling of information allow for moreinformation to be displayed or projected by an output device of a smartring. Additionally, scrolling of information allows for output devicesof a smart ring to display longer messages, whole sentences, and otherindications of information that may not fit onto a display of an outputdevice. In embodiments, a controller or a processor may be configured tocontrol the scrolling of the information projected by an output device,such as the projector modules 490 a, 490 b, 490 c, and/or 490 d.

In embodiments, a processor of the smart ring including a projectormodule may be configured to cause the projector module to scroll theinformation across a surface according to user inputs received at thesmart ring. The user inputs may cause the processor to initiatescrolling, halt scrolling, increase the speed of the scrolling, ordecrease the speed of the scrolling, among other potential scrollingcommands and functionalities.

At block 552, the smart ring receives, at a user input unit such as theuser input unit 170, an initial user input to initiate the scrolling ofprojected information. In embodiments, the user input unit 170 mayinclude a haptic sensor, a microphone or audio sensor, an opticalsensor, a pressure sensor, an accelerometer, a button, a switch, anorientation sensor that detects the physical orientation of the smartring, or another sensor. In embodiments, the user input may include ahaptic input, audio input (e.g., audio command from a user), a currentphysical orientation of the smart ring, a change in orientation of thesmart ring, an activation of a button, an activation of a switch, acaptured image (e.g., an image of a user looking at the smart ring),etc. At block 554, the smart ring initiates the scrolling of theprojected information.

After initiation of the scrolling of the projected information, the userinput unit 170 may receive a secondary user input at block 556, atertiary user input at block 558, or a halting user input at block 560.At block 562, the processor may cause the projector module to increasethe scrolling speed of the projected information in response toreceiving the secondary user input at block 556. Alternatively, at block564, the processor may cause the projector module to decrease thescrolling speed in response to receiving the tertiary user input atblock 558. Additionally, at block 564, the processor may cause theprojector module to halt the scrolling in response to receiving thehalting user input at block 560. At block 568, the processor checks tosee if an end condition has been met. The end condition may include thescrolling of the entire message or projected information, a change inorientation of the smart ring device, a sensor input (e.g., imaging of auser face observing/not observing the output device 490, haptic inputsuch as clenching of a fist, rotation of ring, a change in theorientation of the smart ring, etc.), a timing out of a display time forthe projected information, etc. At block 568, if the terminatingcondition has been met, the processor may cause the projector module tostop presenting the information and may cause the smart ring device toresume previous displays projected by the projector module, or may causethe projector module to display other messages, images, or projectedinformation. Otherwise, if the terminating condition has not been met,the current scrolling state (e.g., speeding up the scrolling, halting ofthe scrolling, etc.) may be applied and the projected information maycontinue to scroll, or otherwise be displayed, and further user inputsmay be received by the user input unit 170.

Additionally, the method 500 may include a block or step (not shown) inwhich a terminating user input is received by the user input unit 170 atany time during the method 500. The terminating user input may cause theprocessor to directly proceed to block 570, thereby endingimplementation of the method 500.

Examples of each of the secondary, tertiary, and halting user inputsinclude: a haptic input, audio input (e.g., audio command from a user),a current physical orientation of the smart ring, a change inorientation of the smart ring, an activation of a button, an activationof a switch, a captured image (e.g., an image of a user looking at thesmart ring), etc. Each of the user inputs may be dependent on a currentstate of the scrolling (e.g., a currently halted scrolling, a currentspeed of the scrolling, etc.). Additional functionalities are alsoenvisioned such as a rewinding of the scrolling allowing a user of thesmart ring device to review information that has already scrolled off ofthe projection.

In embodiments, the output unit 190 of FIG. 1, the output devices 390 a,390 b, 390 c, 390 d, 390 e, 390 f, and/or 390 g, and/or the outputdevice 490, may include LEDs as optical sources for projector modules,and may be configured to illuminate the LEDs in specific patterns,generating an optical signal, to transmit information from a smart ringto another device or system. For example, the LEDs may generate opticalpulses that transmit bits of information to an optical sensor toidentify a user of the smart ring. In other examples, a projector moduleof the output units 190 may display coded information such as a UPCcode, QR code, 2D barcode, PDF417 code, AZTEC code, or another codedimage or graphic to transmit information to an optical sensor toidentify a user of the smart ring. One specific example includescommunication, via an image or optical output from the output unit 190or output devices 390 a, 390 b, 390 c, 390 d, 390 e, 390 f, and/or 390g, the identification of a wearer of the smart ring to a smart lock orelectronic lock of a vehicle. The optical signal received by theelectronic lock may unlock the door depending on a confirmedidentification of the wearer of the smart ring being an approved driverof the vehicle. Another example includes identifying the wearer of thesmart ring to provide permissions to the wearer to operate a vehicle, toobtain statuses of the vehicle parts (e.g., engine performanceinformation, coolant levels, etc.), to obtain a list or timestamped listof previous drivers of the vehicle, to obtain a history of maintenancesperformed on a vehicle, etc. Permissions may include providing access toan account associated with the wearer of the ring to transmit data andinformation from the smart ring device to a device (e.g., cellulardevice, network, laptop, etc.) accessing the account associated with thewearer of the smart ring, or to transmit data and information from adevice accessing the account associated with the wearer of the smartring to the smart ring device. The optical signal (e.g., captured image,optical pulse, etc.) may be used to identify a user for logging intodevices and computers, determining permissions to enter a room,permissions to open a cabinet or closet, identification and permissionsat a medical facility, identification and permissions at an educationalinstitution, clocking into/out of a work place, and identification foroperation of a vehicle, among other identification purposes.

In embodiments, thelogin and verification may be typed onto a virtual keyboard as describedabove. In other embodiments, either or both of the user login andverification may be a physical gesture performed by the user andreceived by an optical sensor of the user input unit 170. For example, avirtual use handshake with a sequence of multiple hand gestures mayconstitute the user login and/or verification. For example, signlanguage may be used as a visual input to act as the user input to theuser input unit 170. The out unit 190 may display a security questionneeding a specific answer to be entered via a virtual keyboard or byother means as described herein. In embodiments, the user input mayinclude one or more of a hand gesture, a hand movement, an inputperformed by a stylus, a gesture performed on a surface with aprojection on the surface, with another virtual interaction with aprojection, or another optical input or virtual projection basedinteraction.

For example, it is contemplated that any or allof these hardware, software, and firmware components could be embodiedexclusively in hardware, exclusively in software, or in any combinationof hardware and software. Accordingly, while the example systemsdescribed herein are described as being implemented in software executedon a processor of one or more computer devices, persons of ordinaryskill in the art will readily appreciate that the examples provided arenot the only way to implement such systems.

The described functions may be implemented, in whole or in part, by thedevices, circuits, or routines of the system 100 shown in FIG. 1. Eachof the described methods may be embodied by a set of circuits that arepermanently or semi-permanently configured (e.g., an ASIC or FPGA) toperform logical functions of the respective method or that are at leasttemporarily configured (e.g., one or more processors and a setinstructions or routines, representing the logical functions, saved to amemory) to perform the logical functions of the respective method.

While the present disclosure has been described with reference tospecific examples, which are intended to be illustrative only and not tobe limiting of the present disclosure, it will be apparent to those ofordinary skill in the art that changes, additions or deletions may bemade to the disclosed embodiments without departing from the spirit andscope of the present disclosure.

Throughout this specification, plural instances may implementcomponents, operations, or structures described as a single instance.Although individual operations of one or more methods are illustratedand described as separate operations, one or more of the individualoperations may be performed concurrently in certain embodiments.

As used herein, any reference to “one embodiment” or “an embodiment”means that a particular element, feature, structure, or characteristicdescribed in connection with the embodiment is included in at least oneembodiment. The appearances of the phrase “in one embodiment” in variousplaces in the specification may not be all referring to the sameembodiment.

As used herein, the terms “comprises,” “comprising,” “includes,”“including,” “has,” “having” or any other variation thereof, areintended to cover a non-exclusive inclusion. For example, a process,method, article, or apparatus that comprises a list of elements may notbe limited to only those elements but may include other elements notexpressly listed or inherent to such process, method, article, orapparatus.

X. General Terms and Phrases

Throughout this specification, some of the following terms and phrasesare used.

Bus according to some embodiments: Generally speaking, a bus is acommunication system that transfers information between componentsinside a computer system, or between computer systems. A processor or aparticular system (e.g., the processor 454 of the server 450) orsubsystem may communicate with other components of the system orsubsystem (e.g., the components 452 and 456) via one or morecommunication links. When communicating with components in a sharedhousing, for example, the processor may be communicatively connected tocomponents by a system bus. Unless stated otherwise, as used herein thephrase “system bus” and the term “bus” refer to: a data bus (forcarrying data), an address bus (for determining where the data should besent), a control bus (for determining the operation to execute), or somecombination thereof. Depending on the context, “system bus” or “bus” mayrefer to any of several types of bus structures including a memory busor memory controller, a peripheral bus, or a local bus using any of avariety of bus architectures. By way of example, and not limitation,such architectures include Industry Standard Architecture (ISA) bus,Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, VideoElectronics Standards Association (VESA) local bus, and PeripheralComponent Interconnect (PCI) bus also known as Mezzanine bus.

Communication Interface according to some embodiments: Some of thedescribed devices or systems include a “communication interface”(sometimes referred to as a “network interface”). A communicationinterface enables the system to send information to other systems and toreceive information from other systems, and may include circuitry forwired or wireless communication.

Each described communication interface or communications unit (e.g.,communications unit 160) may enable the device of which it is a part toconnect to components or to other computing systems or servers via anysuitable network, such as a personal area network (PAN), a local areanetwork (LAN), or a wide area network (WAN). In particular, thecommunication unit 160 may include circuitry for wirelessly connectingthe smart ring 101 to the user device 104 or the network 105 inaccordance with protocols and standards for NFC (operating in the 13.56MHz band), RFID (operating in frequency bands of 125-134 kHz, 13.56 MHz,or 856 MHz to 960 MHz), Bluetooth (operating in a band of 2.4 to 2.485GHz), Wi-Fi Direct (operating in a band of 2.4 GHz or 5 GHz), or anyother suitable communications protocol or standard that enables wirelesscommunication.

Communication Link according to some embodiments: A “communication link”or “link” is a pathway or medium connecting two or more nodes. A linkbetween two end-nodes may include one or more sublinks coupled togethervia one or more intermediary nodes. A link may be a physical link or alogical link. A physical link is the interface or medium(s) over whichinformation is transferred, and may be wired or wireless in nature.Examples of physicals links may include a cable with a conductor fortransmission of electrical energy, a fiber optic connection fortransmission of light, or a wireless electromagnetic signal that carriesinformation via changes made to one or more properties of anelectromagnetic wave(s).

A logical link between two or more nodes represents an abstraction ofthe underlying physical links or intermediary nodes connecting the twoor more nodes. For example, two or more nodes may be logically coupledvia a logical link. The logical link may be established via anycombination of physical links and intermediary nodes (e.g., routers,switches, or other networking equipment).

A link is sometimes referred to as a “communication channel.” In awireless communication system, the term “communication channel” (or just“channel”) generally refers to a particular frequency or frequency band.A carrier signal (or carrier wave) may be transmitted at the particularfrequency or within the particular frequency band of the channel. Insome instances, multiple signals may be transmitted over a singleband/channel. For example, signals may sometimes be simultaneouslytransmitted over a single band/channel via different sub-bands orsub-channels. As another example, signals may sometimes be transmittedvia the same band by allocating time slots over which respectivetransmitters and receivers use the band in question.

Memory and Computer-Readable Media according to some embodiments:Generally speaking, as used herein the phrase “memory” or “memorydevice” refers to a system or device (e.g., the memory unit 144)including computer-readable media (“CRM”). “CRM” refers to a medium ormedia accessible by the relevant computing system for placing, keeping,or retrieving information (e.g., data, computer-readable instructions,program modules, applications, routines, etc.). Note, “CRM” refers tomedia that is non-transitory in nature, and does not refer todisembodied transitory signals, such as radio waves.

The CRM may be implemented in any technology, device, or group ofdevices included in the relevant computing system or in communicationwith the relevant computing system. The CRM may include volatile ornonvolatile media, and removable or non-removable media. The CRM mayinclude, but is not limited to, RAM, ROM, EEPROM, flash memory, or othermemory technology, CD-ROM, digital versatile disks (DVD) or otheroptical disk storage, magnetic cassettes, magnetic tape, magnetic diskstorage or other magnetic storage devices, or any other medium which canbe used to store information, and which can be accessed by the computingsystem. The CRM may be communicatively coupled to a system bus, enablingcommunication between the CRM and other systems or components coupled tothe system bus. In some implementations the CRM may be coupled to thesystem bus via a memory interface (e.g., a memory controller). A memoryinterface is circuitry that manages the flow of data between the CRM andthe system bus.

Network according to some embodiments: As used herein and unlessotherwise specified, when used in the context of system(s) or device(s)that communicate information or data, the term “network” (e.g., thenetworks 105 and 440) refers to a collection of nodes (e.g., devices orsystems capable of sending, receiving or forwarding information) andlinks which are connected to enable telecommunication between the nodes.

Each of the described networks may include dedicated routers responsiblefor directing traffic between nodes, and, optionally, dedicated devicesresponsible for configuring and managing the network. Some or all of thenodes may be also adapted to function as routers in order to directtraffic sent between other network devices. Network devices may beinter-connected in a wired or wireless manner, and network devices mayhave different routing and transfer capabilities. For example, dedicatedrouters may be capable of high volume transmissions while some nodes maybe capable of sending and receiving relatively little traffic over thesame period of time. Additionally, the connections between nodes on anetwork may have different throughput capabilities and differentattenuation characteristics. A fiberoptic cable, for example, may becapable of providing a bandwidth several orders of magnitude higher thana wireless link because of the difference in the inherent physicallimitations of the medium. If desired, each described network mayinclude networks or sub-networks, such as a local area network (LAN) ora wide area network (WAN).

Node according to some embodiments: Generally speaking, the term “node”refers to a connection point, redistribution point, or a communicationendpoint. A node may be any device or system (e.g., a computer system)capable of sending, receiving or forwarding information. For example,end-devices or end-systems that originate or ultimately receive amessage are nodes. Intermediary devices that receive and forward themessage (e.g., between two end-devices) are also generally considered tobe “nodes.”

Processor according to some embodiments: The various operations ofexample methods described herein may be performed, at least partially,by one or more processors (e.g., the one or more processors in theprocessor unit 142). Generally speaking, the terms “processor” and“microprocessor” are used interchangeably, each referring to a computerprocessor configured to fetch and execute instructions stored to memory.By executing these instructions, the processor(s) can carry out variousoperations or functions defined by the instructions. The processor(s)may be temporarily configured (e.g., by instructions or software) orpermanently configured to perform the relevant operations or functions(e.g., a processor for an Application Specific Integrated Circuit, orASIC), depending on the particular embodiment. A processor may be partof a chipset, which may also include, for example, a memory controlleror an I/O controller. A chipset is a collection of electronic componentsin an integrated circuit that is typically configured to provide I/O andmemory management functions as well as a plurality of general purpose orspecial purpose registers, timers, etc. Generally speaking, one or moreof the described processors may be communicatively coupled to othercomponents (such as memory devices and I/O devices) via a system bus.

The performance of certain of the operations may be distributed amongthe one or more processors, not only residing within a single machine,but deployed across a number of machines. In some example embodiments,the processor or processors may be located in a single location (e.g.,within a home environment, an office environment or as a server farm),while in other embodiments the processors may be distributed across anumber of locations.

Words such as “processing,” “computing,” “calculating,” “determining,”“presenting,” “displaying,” or the like may refer to actions orprocesses of a machine (e.g., a computer) that manipulates or transformsdata represented as physical (e.g., electronic, magnetic, or optical)quantities within one or more memories (e.g., volatile memory,non-volatile memory, or a combination thereof), registers, or othermachine components that receive, store, transmit, or displayinformation.

Although specific embodiments of the present disclosure have beendescribed, it will be understood by those of skill in the art that thereare other embodiments that are equivalent to the described embodiments.Accordingly, it is to be understood that the present disclosure is notto be limited by the specific illustrated embodiments.
